Hi We have deployed our application in Windows 7 64 bit machine.We are connecting to Oracle server through 32 bit client then it is giving execption like "Unable to load C:\oracle\product\11.2.0\INTPL11G\bin\oci.dll. Please check that you use 64x version of Oracle client with 64x application.".
Please let us know if any settings needed so that we can connect with 32 client.

Only a 32-bit application can interoperate with a 32-bit Oracle Client. Please open Windows Task Manager on your Windows 7 64-bit machine and check the mode (x86 or x64) the process of your application is executed in. Probably it is x64. If so, please rebuild your project with the Platform target: x86 option specified in the project's properties.
